Claims

[Claims for Utility Model Registration] A suction hand for a robot that uses a plurality of suction pads to suction and convey a thin sheet metal that is pressed against a positioning block on a table for positioning, wherein at least one of the plurality of suction pads is rotated and unidirectionally moved. a biasing means for biasing the movable suction pad toward the one side; and detecting the amount of movement of the suction pad that moves against the biasing force of the biasing means. A suction hand for a robot, characterized in that the suction hand for a robot is provided with a sensor, and the thin sheet metal is suctioned by one of the movable suction pads during the positioning.
